I think 14 marker lights are enough for the list. I also think that you need an aegis and some broadsides. Also those piranhas have inordinate amount of firepower to add to the list. Anything that moves within 24" of the drones will die ... wraiths, wolves, anything, as they get [more shots, wound well, and have better BS]. Send in your decurion wraiths.
The ethereals have three uses:
-Storm of Fire means a potential 90 sniper shots - yes that is 108 sniper shots within 24". This also grants the FW extra shots too. At 15" they get 33 shots. WTF - that is 138 shots at a high BS.
-Ethereals can grant [a survivability bonus]
-Ethereals can [do so much to help nearby units from fleeing].
One thing that is useful to note is that many lists rely on a character to buff or a character to cast psychic spells. Sniper lists are great counters for those type of lists and this list has potential alpha strike capacity.
The vindicare and emp on the fire warriors are late additions to handle IKs monoliths and other AV14. It became aware that there was just not enough heavy AT. One Eye Open stings like a be-atch so place the assassin carefully. They have range, infiltrate and 4++ so it should not be a problem.
And finally .. piranhas have jink. Sniper teams have stealth. Kroot have steath (forests if there are any). Aegis provides cover. So the list is not that easy to kill.
